A unicellular, prokaryotic organism is discovered by scientists. Are these characteristics enough to place it in a domain, or is more information needed?
A unicellular, prokaryotic organism is discovered by scientists. Are these characteristics enough to place it in a domain, or is more information needed?
a) More information is needed because it could be a member of Bacteria or Archaea.
b) More information is needed because it could be a member of Eukarya or Archaea.
c) These characteristics are enough because it can be determined to be a member of Bacteria.
d) These characteristics are enough because it can be determined to be a member of Eukarya.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

Can bacteria reproduce in a way such that when you start out with two bacteria, you get five bacteria? why or why not? * a. yes, because bacteria reproduce sexually, and can produce any number of offspring, just as humans do. b. no, because bacteria grow at an exponential rate. c. no, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria.
